Terrariums have been popping up everywhere lately, and honestly, it makes total sense. They’re tiny green worlds, easy to care for, and a simple way to bring more life indoors. Since we’re big plant people (and yes, there are plants all over our offices), we started thinking about how to mix our love for greenery with our love for reuse. That’s how this DIY came to be. By turning an empty 2-liter soda bottle into a terrarium, you get a little ecosystem that’s both plant-happy and planet-friendly. Let’s get into it.

Choosing the Right Plants and Soil

Terrariums do best with plants that enjoy humidity and steady moisture. Look for varieties that stay small and don’t mind cozy conditions, like umbrella plants or peperomia. These types naturally adapt to enclosed spaces and help create a balanced little environment inside the bottle.

For soil, keep it simple and nourishing. Organic potting soil paired with layers of sand, pebbles, and activated charcoal helps manage moisture and keeps things fresh over time. Each layer has a purpose, and together they create a happy home for your plants.

When the foundation is right, your terrarium mostly takes care of itself.

Soda Bottle Terrarium DIY: Instructions

Step 1: Mark your bottle

Wrap a rubber band around the bottle just below where it starts to curve outward. Take a moment to level it out. This will be your cutting guide.

Step 2: Cut the bottle

Carefully start your cut with a box cutter, then switch to scissors to cut all the way around. Trim about an inch off the bottom of the top piece so it slides back on easily later.

Step 3: Add sand

Pour a thin layer of sand into the bottom of the bottle, about half an inch deep.

Step 4: Add pebbles

Add a layer of pebbles on top of the sand. This helps excess water drain away from the roots.

Step 5: Add activated charcoal

Sprinkle in a thin layer of activated charcoal. This keeps the terrarium fresh and helps prevent unwanted mold.

Step 6: Add organic soil

Add two to three inches of organic soil. Gently poke small holes where your plants will go. We always choose organic when possible, for the plants and the planet.

Step 7: Plant your greenery

Carefully separate your plants and nestle them into the soil. Add a small splash of water to help everything settle in.

Step 8: Decorate

This is where your terrarium becomes yours. Add crystals, glass beads, small figurines, or anything that brings a little joy. Finish with a few extra pebbles on top.

Step 9: Close it up

Gently slide the top portion of the bottle back over the base to seal your mini world.

Step 10: You’re done

Place your terrarium in bright, indirect light. Water lightly every couple of weeks and let it do its thing.
